ADF vs HTML: How Atlassian Structures Rich Text

If you’ve ever worked with Atlassian products like Jira or Confluence Cloud, you’ve likely come across the mysterious Atlassian Document Format (ADF) — a JSON-based schema that powers how rich text and structured content are stored and rendered.

At first glance, ADF looks nothing like HTML. Instead of <p>, <strong>, and <ul>, you’ll find nested objects like "type": "paragraph" or "marks": [{"type": "strong"}]. But ADF isn’t just another markup language — it’s a purpose-built, structured representation of content designed for modern collaborative editing.
